Keep your Mac up to date

Periodically, Apple releases updates to your macOS software (which can include updates to apps that come with your Mac and important security updates).

If you receive a notification that software updates are available, you can choose when to install the updates, or choose to be reminded the next day. You can also check for macOS updates manually in the Software Update pane of System Preferences.

To check for updates to software you’ve downloaded from the App Store, open the App Store.
